Ace, Sabo and Luffy help Naguri make a pirate ship. The three brothers meet the tiger they fought in the previous episode; they defeat the tiger and say good-bye to Naguri. The episode ends with Bluejam ordering his crew to tell Sabo's father that they have found Sabo.
Ace and Sabo get chased by the tiger because Ace attacked the tiger. It had been a week since Ace and Sabo have seen Luffy when they reunite. Naguri has a flashback to his loss to Gol D. Roger, but Ace has met many people who hate Roger and gets angry and attacks Naguri. After a quick battle between Ace and Naguri, Luffy, Ace and Sabo train while they help make the pirate ship for Naguri. Once the long training is done with, it is time for them to fight the big tiger. Ace and Sabo fail to defeat it at first, and Luffy is about to get killed by the tiger when Ace and Sabo stop its paw. They all decide that they must work together to defeat it.
Sabo distracts the tiger while Luffy makes a slingshot with his gomu gomu no mi powers. Sabo gets the tiger to run toward the slingshot, and Ace crouches into the slingshot load; Luffy lets go and performs a "Gomu Gomu No Rocket". Ace is able to defeat the tiger. In the end, Ace decides all three of them helped to defeat the tiger, so no one is officially the captain. Naguri then heads out to sea. The episode ends with Bluejam telling his crew mates to tell Sabo's father that they found him.
